Unit Test failing on missing module via Angular dependency injection

I'm trying to create a simple Unit Test which accesses a factory called LimboExpenseService.

angular.module( 'Trackee').factory( 'LimboExpenseService', require( './services/LimboExpenseService'))

My test looks like:

describe('LimboService', function() {
    var Limbo;
    beforeEach(module('Trackee'));


    it('should have a LimboExpenseService ', inject(['LimboExpenseService', function(LimboExpenseService) {
        expect(LimboExpenseService).toBeUndefined();
    }])); 
});

Problematically, I can't seem to grab that item via the inject() method.

What am I missing here?
